To all whom it may concern:

Be it known that I, Eiuii'a M. GLEVENGER, a citizen "of the UnitedStates, residing at Muneie. in the county of Delaware and State ofIndiana, have invented certain new and Construction, of whichthefollowing is a specifica-' tion.

'lhis'invention relates to improvements in p panied by the improved formand structure of sash bar and lid and the fastening means thereforSllOWl'l'lll the drawing-"Thesash alur'ninui i,- 1 and "has the generalst'ri'ictur'e' shown in the" idiawing fit I window constniction1- T henecessity and: importance fP1OV1d-' mg means at windows for "ventilatingthe room havlong been rec'o'gnized. "Many die j ferent idcyices-h'avbeeii 'develop'c t for? ie p u rp'ose of permitting 'a flow of airthrough thewindow without having to open or shi thesash frames, but'I amnot aware thatas yet any device so brought out has pi-oven suflicieutlypracticable to be adopted by ar -.hitect s and builders, and'e nploy' edsi' cc'css fully in ordinary building con'strli'ietiong,

The objectsfof myinvention are to pro; vide sucli improvei'nents inwindow contruction, that ventilation for living ,rooin's, publicassembly halls, hospitals,-and'the like, may l e/facilitated. To do thisIprovide a member to constitute the bottom barot the uppersash thatis'capable of permittingthe passage of air therethrough, and myinvention accordingly consists of a sash bar ha-v ing an openingtherein, a lid to chase the opening and fastening means whereby the lidis capable of being easily opened and also it may be locked securely;and at the same time the device will notatiect theconstruction or hinderthe regular useand function of either of the sash frames constitutingthe window.

My invention is described in the following specification. defined in theappended claims and illustrated in the accompanyiup, drawings. I

' The several parts of the device as slwwn in the different views aredesignated by similar characters of reference.

In the drawings, Figure 1. is a perspective view of a portion of awindow. that is equipped with my invention. Fig. 2 is a plan view, andFig. 3 is a front view, and Fig. 4- is an end viewof the sash bar. Fig.5 is an enlarged transverse section-d view taken on the line in Fig. 9..Fig. 6 is a t'ront view, and Fig. 7 is a plan view cn-u largged showingthe locking devices for the aids. r.

and lids F, the locking device having been removed.

Inperfecting my present invention, the

practicable in every use in windows of standard construction andconsisting of ordinary double sash structure as shown in Fig.1. I

The objects of the nvention are accombar ismade of, metal, preferablyFormed in respect and capable of te'gral with thcfiat'body pordominating idea has been to make the same v tion A is a rib A whichservesto stiffen the bar at its rear "81(16 andwhich also consti tutesasuiiicint'bulkof metal. that the] I groove A vvillnot Weaken the body'por'tioii..f75" fThisgroove extends the full distance be- B of the sashand willre'ceive the bottom edge of the glassC tween thenpright barswhen the-sash is glazed. Rising fromthe ends of the harare the tongues Awhich havesnitable holes A; To connect the sash bar securely to theupright bars B and to therebv 'cmnplete the sash frame, the tongues Aare inserted into suitable recesses provided therefor in the bottom endsof the upby dowels or bolts D. A which constitutes the. bar is oi properdepth to front of the sash constitute in the usual way a closure ofthespace between the right sash bars B and are then made fast- Thevertical apron Y whereby air currents may be passed through without thenecessity of moving either of the sashes. To accomplish this additionaladvantage I provide the groups of openings 1). To cover these openingsare provided the lids F. hinged at the studs A" and normally will occupythe closed positions as shown in Figs. 2 and 3, the openings E beingcovered and therefore closed. It is desirable that the the window Theselids are lids will be normally held to the'closed poiio sitions so thatwhen the sash bars are being handled in shipment and transporting, the

- lids will not be in the way, or liable to breakage. Moreover, thelids. shouldbe capable of being so secured atclosed posi; tion thatthey, may notbe raised easily by instruments inserted from outside thewin-.

lock dogs G having their body portions G to lie normally on the upperside of the sash bar. The functions of the lugs G will be presentlydescribed. Provided at the upper edge of the frontal side'of the sashbar is an opening A having a longitudinal offset A The rear wall of thisoffset is slanted slightly as shown in Fig. 8. When the lock dog is atthe position as shown in the detail views, the lug Gr is in tightenedengagement with the rear wall of the offset A, and the main portion G ispressed tightly against the top side of the lid. In turn the lid will beheld tightly in. engagement with the sash bar.

A sash bar so constructed and equipped y tion of a sash bar having anopening therein and a notch at its upper edge provided with an offset, alid hingedly connected to the sash bar'and adapted to cover said:openwith the lids F whereby the openings E may be kept either closed oropened,makes it possible to obtain apassing of air currents through thewindow at intervals of the time 35 and length desired, and without thenecessity of moving either of the sashes, and without the necessity ofattachments or devices of any kind at the window frame or .casement.When the lids are locked in position as shown, the openings-E areeffectively closed and they will be retained so against effort to opensame by instruments from outside the window.

To move the lids to the open position as shown in Fig. l, the lock dogisgrasped at the web G and shifted to the right, the lug of said lid atsaid hinge rod, and a notch being provided in the front side of saidsash bar to' re ister with said-recess and havm" an offset therein, alock dog disposed in said recess and held loosely on the said hinge rodand provided with 9. lug to engage said ofi'set, the'main portion ofsaid dog being adapted to lie normally on the said lid.

2. In window construction, a sash bar having an opening therein, a hingebar journaled adjacent to said opening, a notch in the side of said sashbar and having an offset therein with a beveled seat, a lid having itsedge secured to said hinge rod there 'be- 'ing a recess .in the side ofsaid lid at the hinge rod of length greater than that of the 1 notch,and a lock dog disposed in said recess and held loosely'onthe hinge rodand proivided with a lug to engage said oflfset.

3. In window construction, the combinaing and having a recess at itshinged side, a longitudinal bar across saidrecess and in axial alinementwith thehinge center, and a lock dog held loosely on said bar and havinga lug to engage said offset and its main portion to rest normally on thelid.

In testimon'. whereof I affix my signature in presence of two witnesses.
